PLC-5/30 Controller Front Panell

keyswitch; selects controler mode

channel 1A status indicator (lights green and red)

8-pin mini-DIN, DH+ programming terminal connection parallel to channel 1A

channel 1A communication port; its default configuration is DH+ 2

channel 1B communication port;

its default configuration is remote I/O scanner 2

Install battery here

battery indicator (lights red when the battery is low)

controller RUN/FAULT indicator (green when running; red when faulted)

force indicator (amber when I/O forces are enabled)

channel 0 communication status indicator (green when the channel is communicating)

channel 0-25-pin D-shell serial port; supports standard EIA RS-232C and RS-423 and is RS-422A compatible 1

Use this port with ASCII or DF1 full-duplex, half-duplex master, and half-duplex slave protocols. The port's default configuration supports processor programming:

DF1 point-to-point

one stop-bit

2400 bps

BCC error check

no parity

no handshaking

channel 1B status indicator (lights green and red)

Install memory module here

Use these labels to write information about the channel: communication mode, station addresses, etc.

PLC-5 family member designation

1Channel 0 is optically-coupled (provides high electrical noise immunity) and can be used with most RS-422 equipment as long as:

termination resistors are not used

the distance and transmission rate are reduced to comply with RS-423 requirements

2Configure these 3-pin ports for:

remote I/O scanner,

remote I/O adapter,

DH+ communication

unused
